>From the core dump (that you sent me off-list), it looks like you are
using MUSL libc, rather than glibc:

    blp at sigill:~/nicira/ovs/_build(127)$ ldd ./ovs-vswitchd
            linux-vdso.so.1 (0x00007fff877bd000)
            libssl.so.1.1 => /lib/x86_64-linux-gnu/libssl.so.1.1 (0x00007f6bc4526000)
            libcrypto.so.1.1 => /lib/x86_64-linux-gnu/libcrypto.so.1.1 (0x00007f6bc423e000)
            libcap-ng.so.0 => /lib/x86_64-linux-gnu/libcap-ng.so.0 (0x00007f6bc4236000)
            libc.musl-x86_64.so.1 => not found
            libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f6bc4231000)
            libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f6bc4210000)
            libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f6bc404d000)
            /lib/ld-musl-x86_64.so.1 => /lib64/ld-linux-x86-64.so.2 (0x00007f6bc47fb000)
    blp at sigill:~/nicira/ovs/_build(0)$ 

Is that correct?

But it does not point out any significant memory leaks--even if I consider all of the "possible leaks" it mentions as actual leaks (usually, they are not), they are much too small by orders of magnitudes to be the problem reported.
